Continuing battery problems.

If the battery was really drawing 85mA then that would take just over 2AH out of the battery in 24 hours, which is about 20% of a full charge. On that basis if it's not dropped below 12.5V at rest in a couple of days then it can't have been drawing that current all the time. Bear in mind that every time you discharge a battery below about 50% you are damaging it or at the very least reducing it's life so I wouldn't let it drop to 12V if you can avoid it.

Regarding charging, you're more or less correct assuming you're checking under like circumstances, and allowing the battery to settle down. Checking right after a ride is going to show an artificially high voltage (assuming it's been charging at all).

That's all I erally meant in regards to that, in that if the charge is the same or above the readings before the ride then the charging system must be working. I'd take another reading later on that day or the next morning though just to see what that is.

Well 12.63v this morning so all seems normal. Baffling!! Gonna just plod on as normal and put it on charge as mentioned once a week/night before a ride. I'll still try and get to the bottom of things though. All I can think of is that there's an exposed wire that might intermittently touch metal bodywork or something so depending on how it ends up resting may cause a drain, but what do I know. Sound feasable?

Yes. Frustrating, but I don't see what else you can do. Testing's not going to help except when the fault is occurring.

Maybe more experienced SV'ers can suggest likely places to look for wiring chafe.

Grrrrrrrrrrrrrrrrrrrr!!!

I'm hoping this will be resolved soon as I'm (regretably) hopefully selling the bike soon to upgrade.

Went to start it just for the first time in a couple of weeks. Did a reading first which was showing 12.59v, so battery was still charged. Priming noise etc sounded good, pressed the starter and.....clicking and flashing!! Did a reading straight after this failure and battery was at approx. 11.59v. So after all this messing about, I'm hoping that this now just means new battery time.

Anyway got an opinion? Only other thing I can think of is something to do with the starter but that's always bang on the button when the battery has recently been charged. And as this problem seems to be happening all the time now I think it all adds up to the battery in some way deteriorating.

your battery is fubar. end of. mine was same symptoms, a nice new battery later and all is well. can even leave my alarm on without fear of it draining within 2 days.

Does seem to be the case. Would you go with another Yuasa or another make? Seen an Exide one for a much more favourable price.

Yuasa. just got one at £34 delivered. i do suspect that they are all made in the same factory.
